how can I start a not scheduled job via the API? Could not find a way. Do I really have to create a schedule first? What is meant by the “ReleaseKey”? I would like to just provide a Jobname with the package

One handy way to display it is to simply enter to your browser (when authenticated) search bar, preferably a “modern” one such Firefox or Chrome, orchestratorurl/odata/Releases (case sensitive).

This will display you the json objects, you need to pass your startjob the queue.
Of course you can get the same result if you use http request and loop through the json results to find the key your are looking for.

There are some functions that are not supported directly by UIPath. For example, dependency scheduling is not supported (e.g., start consumer job when producer job completes). So you can use the APIs to have one robot start another as the last step before it completes. Note that functionality differs by UiPath version (newer versions have more features in standard activities that replace the need for some APIs).
Also, due to corporate policies, some developers may not be able to install additional tools (e.g., Postman) so providing working examples of the API calls in existing tools is helpful to simulate an external client using APIs.

Thanks scottl, for the files and clarification.
It seems, from v2018.1 of Studio, there’s also possibility for activity, “Orchestrator HTTP Request” which seems to accept the JSON payload and different REST methods. But, we need to check in detail how best to use the same.activities.uipath.com

`UiPath.Core.Activities.OrchestratorHttpRequest` Performs HTTP requests to the Orchestrator API by authenticating under the Robot it is executed on. You can use the `GET`, `POST`, `PUT`, `PATCH` and `DELETE` verbs to extract data or manipulate it,...

Hi @scottl,
I’ve looked to the files you’ve added and it worked fine for me in order to start a job from UiPath. But, do you have any idea about how to start a job remotly from a browser? I’ve start a new topic about it, maybe you have a great idea of yours
Thanks
